Quick update: Removing the # character from the filename cleared up Problem Number 1. Duh!

Hi Sita,
Thank you for your reply!!
I was wondering if that # character in the movable file name could be creating any problems; I will definitely try it without and keep you updated!
As for the second issue, I was trying to view Subject D10's talairach transformed brain in tkmedit. I followed the instructions on http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach to do so. My command line to open tkmedit was as follows:
tkmedit D10 brainmask.mgz
When the tkmedit GUI opened with the brainmask.mgz as the main volume, I went to File-->Transforms-->Load as Main volume and clicked OK
At this point, a dialog box popped up with the error "couldn't determine type of file /nfs/data17/hansenka/ntopy/surf/D/D10/mri/transforms/talairach.xfm" and the transform did not open.
***HOWEVER the really strange thing is that I had done the exact same order of operations about five minutes earlier to open and view the same subject's talairach transformed volume and everything worked perfectly. I then closed tkmedit and when I tried it again five minutes later the above occurred.***
I know that temporal proximity and similar error messages do not necessarily mean that the two problems are related, but since they are both happening in the same subject's data, it got me wondering.
Please let me know if you have any insights! Thanks so much again!

Hi Elise,
can you try renaming the file Wedges6_r1_D10_0_pi3_1#0_Coef.nii without the special character # and rerun mri_vol2surf. And regarding your second question, what was your command line. Were you trying to apply the transform talairach.xfm to a volume opened in tkmedit.
Sita.

Hi all,
Hopefully this is not too stupid of a question. Something seems to have happened to one of our subjects' surface data, such that when I try to resample the volume Wedges6_r1_D10_0_pi3_1#0_Coef.nii onto subject D10's surface, I get the following error:
mri_vol2surf --mov Wedges6_r1_D10_0_pi3_1#0_Coef.nii --noreshape --reg register.Wedges6_raw_D10.dat --projfrac 0.5 --interp nearest --hemi rh --o Wedges6_r1_D10_0_pi3_1#0_Coef.mgh ERROR: could not determine type of Wedges6_r1_D10_0_pi3_1#0_Coef.nii
Not sure if it is related, but I recently tried opening the same subject's talairach.xfm brain in tkmedit and got a similar error (from the error.log file):
mri_read(): couldn't determine type of file /nfs/data17/hansenka/ntopy/surf/D/D10/mri/transforms/talairach.xfm
Has anyone seen such an error before and/or know how to fix it?
Please let me know! Thank you!!!
